As a young boy, British-born Italian Carlo Acutis was fascinated by miracles.

He read captivating stories about wine turning to blood in Croatian castles and how in Colombia priests stopped approaching tsunamis by holding up reliquaries.

At the age of 11, the devout Catholic began typing up these tales and posting them on his website, which he had designed to document miracles and stories about saints.

In Catholicism, saints are defined as people in heaven who lived righteous lives and used their faith to help others, and in order to become a saint, the individual needs two miracles verified after their death.

Carlo is set to be canonised on Sunday by Pope Leo XIV, but from a young age, the boy was already on the path to sainthood.
